Cannot inspect Hashtable anymore
by Blondeau Vincent
Hello,
I am currently working with Hashtable which is loaded by default in the Moose image.
With the latest image, I tried to do: (HashTable new at: #a put:1;yourself) inspect. And I got an inspector with the red square of death...
It seems that the visualization wants to get the item at the position 1 in the Hashtable but it cannot succeed because there is no item at 1 (obviously, it is an hashtable).
Can someone with GtTools knowledge take a look at that?
Thanks in advance,
Cheers,
Vincent

RTForceBasedLayout without overlapping arbitrary shapes
by Cris Fuhrman
Hello,
Here's an example code using RTForceBasedLayout (from an example on this
list a while back):
------------
view := RTView new.
objects := RTObject withAllSubclasses.
elements := (RTBox new size: #numberOfMethods; color: (Color blue alpha:
0.5)) elementsOn: objects.
elements @ RTPopup new.
view addAll: elements.
RTForceBasedLayout on: elements.
view @ RTDraggableView .
view open
------------
It produces:
[image: Inline image 1]
Is it possible to have the RTForceBasedLayout such that the result has no
overlapping boxes (or rectangles)? I realize setting force: to some large
negative number will help, but it's not ideal because it creates a lot of
empty space.
In d3 (with SVG) there are a couple of examples of what I'd like to achieve
(although they don't show edges):
https://bl.ocks.org/mbostock/1062383 (arbitrary shapes)
https://bl.ocks.org/mbostock/3231298 (arbitrary circles that stick to each
other)
The animation isn't important in my case. I wasn't sure where/how to apply
the transform operation after a layout has been done in RTForceBasedLayout.
Any hints?
Here's what my graph looks like:
[image: Inline image 2]
The code I have to produce this is too much to post, so I used the example
at the top. My code also uses
RTForceBasedLayout new charge: -1000; on: b elements.
Cheers!

Roassal: Locate a legend text below a line
by Hernán Morales Durand
Hi everybody,
I have this complicated code to draw a line with separators at both ends, I
try to put the legend text with #below but nothing is changed :
| view e1 e2 l1 label |
view := RTView new.
label := RTLabeled new
color: Color black;
below;
text: 'Class IIa';
yourself.
e1 := RTBox new element
color: Color black;
height: 10;
width: 1;
yourself.
e2 := RTBox new element
color: Color black;
height: 10;
width: 1;
yourself.
l1 := RTStyledMultiLine new
color: Color black;
solidLine;
edgeFrom: e1 to: e2.
view addAll: (Array with: e1 with: e2 with: l1).
l1 @ label.
RTHorizontalLineLayout new on: view elements.
view elements pairsDo: [ :a :b | b translateBy: 100 @ 0 ].

Any suggestion?

Re: software reingineering guidelines

Hi,
Thank you Nicolas and Anne for the hints/links
@Alex
Yes, genetic algorithms are “abstract” algorithms. I am actually talking about analysing the code of the frameworks for developing different genetic algorithms to solve all kinds of optimisation problems (knapsack, Traveling Salesman Problem but also “real life" problems : image processing, and many artificial intelligence problems)
There are many GA frameworks. Some popular ones are : ECJ (https://cs.gmu.edu/~eclab/projects/ecj/), OpenBeagle (http://vision.gel.ulaval.ca/~parizeau/Publications/beagle-gecco.pdf), WatchMaker (http://watchmaker.uncommons.org/), HeuristicLab (http://dev.heuristiclab.com/)…

Ah ah! Sorry, I read too fast!
But it is not clear what are you referring to when you mention “generic algorithm”? Can you give an example?

Roassal: Why the grey outline?
by Hernán Morales Durand
The attached capture is the one implemented by the method
#exampledoubleCurves.
If you zoom the image you will notice the grey edge of each green and blue
line. The same happens in #exampleVerticalAndHorizontalLines
Is there a way to remove it the grey around each line?

AthensCairoCanvas>>setPaint: receiving a "Color transparent"
by Hernán Morales Durand
I am using stable branch of Roassal2 in Pharo 5 and Win 8.1 to draw a
figure for a paper (but the problem is the same loading the latest versions
SmalltalkHub).
When trying to open a grapher, I get a yellow-cross red morph window inside
#setPaint: . The transparent color passed as argument came from
AthensCairoSurface>>clear
The same figure used to open without problems some months ago.
All the Roassal examples open without problems. That's why here is the link
to the fuel out stack with the halt previous to the crash :
https://dl.dropboxusercontent.com/u/103833630/Debugger-Stack-AthensCairoC...
Is this a well-known bug? Any suggestion?

I was thinking that people from Synectic (for instance) could have some valuable experience in this field (where to start from, a list of what to look for, how to look for it, the different reports, …)

Yes, and use the queries to gets different metrics about the projects. maybe detect some (anti) patterns...

Definitely, this is part of the objectives too :)
Maybe we could produce a sorte of practical guide to code analysis with Moose.

Re: software reingineering guidelines

Hi Alex,
The idea is not to use genetic algorithms to improve software quality. Rather, to use Moose to enhance the design of existing frameworks for genetic algorithms.
I have attached a brief description of the project to this email. It is in french but this is not a problem for you I think :)

Book, Working Effectively with Legacy Code
by Ben Coman
Interesting to see this is the top mentioned book on stackoverflow.
I wonder if Moose can facilitate any of its contained topics
and maybe leverage its popularity.
